The electricity generation process involves a number of energy changes, regardless of the initial energy source that is utilised. Traditionally, electricity has been generated using fossil fuels, especially coal. More recently, power stations have started to use gas and oil as their power source. Oil-fired power stations are widespread in oil producing states, for example Indonesia. Gas burns more cleanly and efficiently than coal. It releases half as much carbon dioxide and more than 1000 times less sulphur dioxide per unit of energy.

Electricity is commonly generated at a degree that meets demand, as it is tough to store surplus energy. However , it’s actually possible to store smaller amounts of energy for private and domestic uses. Batteries and fuel cells both produce electricity by utilizing electrochemical reactions. Flywheels store up power as they spin.
